The Notes may be issued from time to time upon written order of the Company for the authentication and delivery of Notes pursuant to Section 3.3 of the Base Indenture.

Section 2.02 Maturity. Unless a Special Event Redemption has occurred, the Notes will mature and the principal amount thereof shall be due and payable together with all accrued and unpaid interest thereon, on the Stated Maturity. The “Stated Maturity” shall mean June 1, 2014 or such other date as determined by the Company on the Successful Remarketing Date (subject to agreement between the Company and the Remarketing Agent pursuant to the Remarketing Agreement with respect to the Remarketing Fee) in accordance with Section 7.02, it being understood that if there shall have been a Failed Remarketing, the Stated Maturity shall remain June 1, 2014.

Section 2.03 Form, Payment and Appointment. Except as provided in Section 2.04, the Notes shall be issued in fully registered, certificated form, bearing identical terms and registered in the name of the Purchase Contract Agent. Principal of, and premium, if any, and interest on the Notes will be payable, the transfer of such Notes will be registrable, and such Notes will be

exchangeable for Notes of a like aggregate principal amount in denominations of $1,000 (unless Notes have previously been issued in denominations of $50 and integral multiples thereof, in which case Notes will be exchangeable for a like aggregate principal amount in denominations of $50 and integral multiples of $50) and integral multiples of $1,000 bearing identical terms and provisions, at the office or agency of the Company and the Guarantor maintained for such purpose in the Borough of Manhattan, The City of New York, which shall initially be the Corporate Trust Office of the Trustee; provided, however, that payment of interest may be made at the option of the Company or the Guarantor by check mailed to the Holder at such address as shall appear in the Security Register or by wire transfer to an account with a financial institution in the United States appropriately designated by the Holder entitled to payment by notice to the Trustee given at least 15 days prior to the Interest Payment Date.

No service charge shall be made for any registration of transfer or exchange of the Notes, but the Company may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

The Security Registrar and Paying Agent for the Notes shall initially be the Trustee.

The Notes shall be issuable in denominations of $1,000 and integral multiples of $1,000 in excess thereof; provided, however, that upon the release by the Collateral Agent of the Pledged Notes in accordance with Section 3.15 of the Purchase Contract and Pledge Agreement, the Notes shall, if requested by the Purchase Contract Agent, be issuable in denominations of $50 and integral multiples of $50. Each Applicable Ownership Interest in a Note held as a component of a Corporate Unit represents an undivided ownership interest of 1/20, or 5%, of $1,000 principal amount of Notes.

Section 2.04 Global Notes. Notes corresponding to Applicable Ownership Interests in Notes that are no longer a component of the Corporate Units and released from the Collateral Account will be issued in permanent global form (a “Global Note”), and if issued as one or more Global Notes, the Depository shall be The Depository Trust Company or such other depository as any officer of the Company may from time to time designate. On the date on which the Notes registered in the name of the Purchase Contract Agent pursuant to Section 2.03 are issued, the Company shall also issue one or more Global Notes, registered in the name of the Depository or its nominee, each having a zero principal balance. Upon the creation of Treasury Units or the recreation of Corporate Units, an appropriate annotation shall be made on the Schedule of Increases and Decreases on the Global Notes held by or on behalf of the Depository and on the Pledged Note held by the Collateral Agent. Notes represented by the Global Notes will be exchangeable for Notes in certificated form only (a) if the Depository notifies the Company that it is unwilling or unable to continue as Depository for the Global Notes or if at any time the Depository ceases to be a clearing agency registered under the Exchange Act, and the Company has not appointed a successor Depository within 90 days of that notice or of its becoming aware of such cessation or (b) upon recreation of Corporate Units; provided that, subject to the last paragraph of Section 2.03, the Notes in certificated form so issued in exchange for the Global Notes shall be in denominations of $1,000 or any whole multiple of $1,000 above that amount and be of like aggregate principal amount and tenor as the portion of the Global Note to be exchanged. Except as provided above, owners of beneficial interest in a Global Note will not be entitled to receive physical delivery of Notes in certificated form and will not be considered the

Holders thereof for any purpose under the Indenture. Unless and until such Global Note is exchanged for Notes in certificated form, Global Notes may be transferred, in whole but not in part, and any payments on the Notes shall be made, only to the Depository or a nominee of the Depository, or to a successor Depository selected or approved by the Company or to a nominee of such successor Depository. Any Global Note that is exchangeable pursuant to clause (a) of the fourth sentence of this Section 2.04 shall be exchangeable for Notes in certificated form registered in such names as the Depository shall direct.

Section 2.05 Interest. (a) The Notes will bear interest initially at the rate of 8.50% per year (the “Interest Rate”) from the date of original issuance to, but excluding, the earlier of (i) the Stated Maturity and (ii) the Reset Effective Date. In the event of a Successful Remarketing of the Notes, the Interest Rate will be reset by the Remarketing Agent, as set forth under Section 7.02. If the Interest Rate is so reset, the Notes will bear interest at the Reset Rate from the related Reset Effective Date to, but excluding, the Stated Maturity. The Notes shall bear interest, to the extent permitted by law, compounded quarterly or semi-annually, as applicable, on any overdue principal and payment of interest at the Interest Rate through and including the day immediately preceding the Reset Effective Date and at the Reset Rate thereafter.

(b) Interest on the Notes shall be payable initially quarterly in arrears on (i) March 1, June 1, September 1 and December 1 of each year (each, a “Quarterly Interest Payment Date”), commencing on September 1, 2009, and (ii) the Reset Effective Date, but only to the extent such Reset Effective Date is not a Quarterly Interest Payment Date, in each case, to the Person in whose name such Note, or any Predecessor Security, is registered at the close of business on the Record Date for such Interest Payment Date. With respect to clause (ii) of the previous sentence, the Company shall designate a Record Date for such Interest Payment Date no later than 10 Business Days prior to the Record Date selected by the Company. Following a Successful Remarketing of the Notes, interest on the Notes, if the Company so elects on the Successful Remarketing Date, may be payable semi-annually in arrears on the Subsequent Interest Payment Dates (together with Quarterly Interest Payment Dates and the Reset Effective Date, if not a Quarterly Interest Payment Date, the “Interest Payment Dates”). Interest payments will include interest accrued from and including the immediately preceding Interest Payment Date or, in the case of the first Interest Payment Date, from and including June 24, 2009, to but excluding such Interest Payment Date. If the Reset Effective Date is not a Quarterly Interest Payment Date, (i) interest paid on the Reset Effective Date shall be paid to the Collateral Agent and will be released by the Collateral Agent to the Purchase Contract Agent for distribution to Holders of Corporate Units subject to the provisions of the Purchase Contract and Pledge Agreement on the Interest Payment Date for the Corporate Units next following the Reset Effective Date and at the times provided for in Sections 3.13, 4.01(b) and 5.07 of the Purchase Contract and Pledge Agreement, and (ii) interest on the Notes will accrue from, and including, the Reset Effective Date at the Reset Rate and be payable on the Subsequent Interest Payment Dates.

(c) The amount of interest payable for any full quarterly period or any full semi-annual period, as the case may be, will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of interest payable for any period shorter than a full quarterly or semi-annual period, as the case may be, for which interest is computed will be computed on the basis of a 30-day month and, for any period less than a month, on the basis of the actual number of days elapsed per 30-day month. In the event that any scheduled Interest

Payment Date falls on a day that is not a Business Day, then payment of interest payable on such Interest Payment Date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next calendar year, then such payment will be made on the preceding Business Day, in each case, with the same force and effect as if made on such scheduled Interest Payment Date.

Section 2.06 No Defeasance. The provisions of Sections 4.2 of the Base Indenture shall not apply to the Notes.

Section 2.07 No Sinking Fund. The Notes are not entitled to the benefit of any sinking fund.

Section 2.08 Guarantee. The provisions of Article 16 of the Base Indenture shall apply to the Notes.

Section 2.09 Increase and Decrease. In the event that any Notes underlying Applicable Ownership Interests in Notes are to be released from the Pledge following a Collateral Substitution, Early Settlement or Fundamental Change Early Settlement pursuant to the Purchase Contract and Pledge Agreement (a “Released Note”), such release and delivery shall be evidenced by an endorsement by the Collateral Agent on the Pledged Note held by the Collateral Agent reflecting a reduction in the principal amount of such Pledged Note equal in amount (the “Reduced Principal Amount”) to the principal amount of the Released Note. The Collateral Agent shall confirm any such Reduced Principal Amount by telecopying or otherwise delivering a photocopy of such endorsement made on the Pledged Note evidencing such Reduced Principal Amount to the Trustee at the telecopier number or address of the Trustee provided for notices to the Trustee in the Purchase Contract and Pledge Agreement (or at such other telecopier or address as the Trustee shall provide to the Collateral Agent). Upon receipt of such confirmation, the Trustee shall, or shall instruct the Custodial Agent to increase the principal amount of a Global Note held by it or by the Custodial Agent in an amount equal to the Reduced Principal Amount by an endorsement made by it or by the Custodial Agent on such Global Note to reflect such increase. In the event that a Note is transferred to the Collateral Agent pursuant to Section 3.14 of the Purchase Contract and Pledge Agreement (a “Subjected Note”) in connection with the recreation of Corporate Units, such transfer shall be evidenced by an endorsement by the Collateral Agent on the Pledged Note held by the Collateral Agent reflecting an increase in the principal amount of such Pledged Note equal in amount (the “Increased Principal Amount”) to the principal amount of such Subjected Note. The Collateral Agent shall confirm any such Increased Principal Amount by telecopying or otherwise delivering a photocopy of such endorsement made on the Pledged Note evidencing such Increased Principal Amount to the Trustee at the telecopier number or address of the Trustee provided for notices to the Trustee in the Purchase Contract and Pledge Agreement (or at such other telecopier or address as the Trustee shall provide to the Collateral Agent). Upon receipt of such confirmation, the Trustee shall, or shall instruct the Custodial Agent to decrease the principal amount of the Global Note held by it or by the Custodial Agent in an amount equal to the Increased Principal Amount by an endorsement made by it or by the Custodial Agent on such Global Note to reflect such decrease.

ARTICLE III

REDEMPTION OF THE NOTES

Section 3.01 Special Event Redemption. If a Special Event shall occur and be continuing, the Company may, at its option, redeem the Notes in whole, but not in part, on any Interest Payment Date prior to the earlier of the Successful Remarketing Date or the Purchase Contract Settlement Date, at a price per Note equal to the Redemption Price, payable on the date of redemption (the “Special Event Redemption Date”) in accordance with the redemption procedures set forth in Section 3.04 below. The Redemption Price payable in respect of all Notes included in Corporate Units will be distributed to the Collateral Agent, which in turn will apply such Redemption Price to purchase the Special Event Treasury Portfolio on behalf of the Holders of the Corporate Units and remit the remaining portion (net of fees and expenses, if any), if any, of such Redemption Price to the Purchase Contract Agent for payment to the Holders of the Corporate Units. Thereafter, the Applicable Ownership Interests in the Special Event Treasury Portfolio will be substituted for the Applicable Ownership Interests in Notes and will be pledged to the Company through the Collateral Agent to secure the Holders’ obligations to purchase Common Shares under the related Purchase Contract. Holders of Separate Notes will directly receive the Redemption Price with respect to their Separate Note.

Section 3.02 Notice of Special Event Redemption. The Company shall notify the Collateral Agent in writing that that a Special Event has occurred and the Company intends to redeem the Notes on the Special Event Redemption Date. If the Company elects to redeem the Notes in connection with a Special Event Redemption, the Company shall appoint the Quotation Agent to assist the Company in determining the Treasury Portfolio Purchase Price.

Section 3.03 Effect of Redemption. Notice of Special Event Redemption having been given as provided for in Section 11.4 of the Base Indenture, the Notes shall become due and payable on the Special Event Redemption Date at the Redemption Price. Unless the Company defaults in the payment of the Redemption Price, on and after the Special Event Redemption Date, once notice of Special Event Redemption is so given and funds are irrevocably deposited, in each case, in accordance with Section 3.04, (a) interest shall cease to accrue on the Notes immediately prior to the close of business on the Special Event Redemption Date, (b) the Notes shall no longer be Outstanding and (c) all rights of the Holders in respect of the Notes shall terminate and lapse (other than the right to receive the Redemption Price upon surrender of such Notes but without interest on such amount). Following the notice of Special Event Redemption, neither the Company nor the Trustee shall be required to register the transfer of or exchange the Notes to be redeemed.

Section 3.04 Redemption Procedures. On or prior to 11:00 a.m., New York City time, on the Special Event Redemption Date, the Company or the Guarantor shall deposit with the Trustee or with a Paying Agent immediately available funds in an amount sufficient to pay, on the Special Event Redemption Date, the aggregate Redemption Price for all outstanding Notes. If the Company has paid to the Trustee a sufficient amount of cash in connection with the related Special Event Redemption Date of the Notes, then, if the Notes are Global Notes, on the Special Event Redemption Date, the Trustee will irrevocably deposit with the Depository funds sufficient to pay the Redemption Price for the Notes being redeemed. The Company will also

give the Depository irrevocable instructions and authority to pay the Redemption Price in immediately available funds to the holders of beneficial interests in the Global Notes. If any Special Event Redemption Date is not a Business Day, then the Redemption Amount will be payable on the next Business Day (and without any interest or other payment in respect of any such delay). However, if payment on the next Business Day causes payment of the Redemption Amount to be in the next calendar year, then payment will be on the immediately preceding Business Day, in each case with the same force and effect as if made on that payment date. Interest to be paid on or before the Special Event Redemption Date for any Notes called for Special Event Redemption shall be payable to the Holders on the Record Dates for the related Interest Payment Dates.

Section 3.05 No Other Redemption. Except as set forth in this Article 3, the Notes shall not be redeemable by the Company prior to the Maturity Date. Except for Sections 11.2 and 11.4, the remaining redemption provisions of Article 11 of the Base Indenture shall not apply to the Notes.

ARTICLE IV

The Notes and the Trustee’s Certificate of Authentication to be endorsed thereon are to be substantially in the form attached as Exhibit A hereto, with such changes to the Notes as the officers of the Company executing the Notes (by manual or facsimile signature) may approve, such approval to be conclusively evidenced by their execution thereof.

ARTICLE V

(1) but for the relevant Holder (or the beneficial owner of such Notes) (i) having any present or former connection with the Taxing Jurisdiction, including, without limitation, being or having been a citizen or resident thereof, or having been present, having been incorporated in, having engaged in a trade or business or having (or having had) a permanent establishment or principal office therein, (ii) being a controlled foreign corporation within the meaning of Section 957(a) of the Code related within the meaning of Section 864(d)(4) of the Code to the Company or the Guarantor, (iii) being an actual or constructive owner of 10 percent or more of the total combined voting power of all classes of stock of the Company or the Guarantor entitled to vote, (iv) being a bank for United States federal income tax purposes whose receipt of interest on the Note is described in Section 881(c)(3)(A) of the Code or (v) being subject to backup withholding as of the date of the purchase by the Holder of the Note;

(2) but for the failure of the relevant Holder (or the beneficial owner of such Notes) to use its reasonable best efforts, to the extent such Holder (or beneficial owner) is legally entitled to do so, to comply upon written notice by the Company or the Guarantor delivered 60 days prior to any payment date with a request to satisfy any certification, identification or other reporting requirements, which shall include any applicable forms or instructions, whether imposed by statute, treaty, regulation, or administrative practice, concerning the nationality or residence of such Holder or the connection of such Holder with the Taxing Jurisdiction;

(3) but for an election by the Holder of such Notes, the effect of which is to make one or more payments in respect of such Notes subject to United States federal income tax or withholding tax provisions;

(4) if the payment could have been made without such deduction or withholding if the relevant Holder had presented such Note for payment within 30 days

after the date on which such payment became due and payable or the date on which payment thereof is duly provided for, whichever is later (except to the extent that the Holder would have been entitled to Additional Amounts had such Note been presented on the last day of such 30-day period);

(5) with respect to any payment of principal of (or premium, if any, on) or interest on such Note to any Holder who is a fiduciary or partnership or any person other than the sole beneficial owner of such payment, to the extent that a beneficiary with respect to such fiduciary, a member of such a partnership or the beneficial owner of such payment would not have been entitled to the Additional Amounts had such beneficiary, member or beneficial owner been the actual Holder of such Note (but only if there is no material cost or expense associated with transferring such Notes to such beneficiary, partner or beneficial owner and no restriction on such transfer that is outside the control of such beneficiary, partner or beneficial owner); and

(6) any combination of items (1), (2), (3), (4) or (5) above

REMARKETING

Section 7.01 Remarketing Procedures. (a) Pursuant to the Remarketing Agreement and as described below, the Company (i) during the Period for Early Remarketing may, at its option, select one or more Three-Business Day Remarketing Periods consisting of three successive Remarketing Dates on each of which it shall cause the Remarketing Agent to remarket, in whole (but not in part), unless the Notes have previously been successfully remarketed in accordance with the provisions of the Remarketing Agreement or a Special Event Redemption shall have occurred or will occur on or prior to the last possible Remarketing Date related to the applicable Three-Business Day Remarketing Period, (A) the Pledged Notes of Corporate Units Holders included in the Corporate Units, and (B) any Separate Notes of Holders who have elected in the manner set forth in the Purchase Contract and Pledge Agreement and the Remarketing Agreement to have their Notes so remarketed, for settlement on the Reset Effective Date, and (ii) shall, unless the Notes have previously been successfully remarketed in accordance with the provisions of the Remarketing Agreement or a Special Event Redemption Date shall have occurred or will occur on or prior to the Purchase Contract Settlement Date, cause the Remarketing Agent to remarket, in whole (but not in part), on each Remarketing Date during the Final Three-Business Day Remarketing Period, (A) the Pledged Notes of Corporate Unit Holders who have not already settled the Purchase Contracts included in their Corporate Units and who have failed to notify the Purchase Contract Agent, on or prior to the seventh Business Day immediately preceding the Purchase Contract Settlement Date, of their intention to settle such Purchase Contracts in cash, and (B) any Separate Notes of Holders who have elected in the manner set forth herein to have their Notes so remarketed, for settlement on the Purchase Contract Settlement Date. The Company may select a Three-Business Day Remarketing Period during the Period for Early Remarketing by designating each of the three sequential Remarketing Dates to comprise such Three-Business Day Remarketing Period; provided that no Remarketing Date during the Period for Early Remarketing shall occur earlier than December 1, 2011 or later than May 1, 2012.

(b) The Company will request, not less than 10 Business Days prior to each Remarketing Announcement Date, that the Depository (or any successor or its nominee) notify the Depository participants holding Notes, Corporate Units and Treasury Units of the Remarketing.

(c) On the Remarketing Announcement Date, the Company shall make an announcement regarding the proposed Remarketing of the Notes (the “Remarketing Announcement”). The Remarketing Announcement shall specify the following:

(i) (A) if the Remarketing Announcement relates to a Remarketing to occur during the Period for Early Remarketing, that the Notes may be remarketed on any or all of the sixth, seventh and eighth Business Days following such Remarketing Announcement Date; or

(B) if the Remarketing Announcement relates to a Remarketing to occur during the Final Three-Business Day Remarketing Period, that the Notes may be remarketed on any or all of the third, fourth and fifth Business Days following such Remarketing Announcement Date;

(ii) (A) if the Remarketing Announcement relates to a Remarketing to occur during the Period for Early Remarketing, that the Reset Effective Date will be the third Business Day following the Remarketing Date on which the Notes are successfully remarketed unless there is a Successful Remarketing within five Business Days of the next succeeding Interest Payment Date, in which case such Interest Payment Date will be the Reset Effective Date; or

(B) if the Remarketing Announcement relates to a Remarketing to occur during the Final Three-Business Day Remarketing Period, that the Reset Effective Date will be the Purchase Contract Settlement Date if there is a Successful Remarketing;

(iii) that the Reset Rate and Subsequent Interest Payment Dates for the Notes will be established, and if the Company elects to make any Modifications to the terms of the Notes as provided in Section 7.02, that such Modifications will be set on the Successful Remarketing Date and effective on and after the Reset Effective Date;

(iv) (A) if the Remarketing Announcement relates to a Remarketing to occur during the Period for Early Remarketing, that the Reset Rate will equal the interest rate on the Notes that will enable the Notes to be remarketed at a price (the “Remarketing Price”) equal to at least 100% of the sum of the Remarketing Treasury Portfolio Purchase Price and the Separate Notes Purchase Price, plus the applicable Remarketing Fee; or

(B) if the Remarketing Announcement relates to a Remarketing to occur during the Final Three-Business Day Remarketing Period, that the Reset Rate will equal the interest rate on the Notes that will enable the Notes to be remarketed at a price (the “Contract Settlement Price”) equal to at least 100% of their aggregate principal amount, plus the applicable Remarketing Fee; and

(v) the possible ranges of the Remarketing Fee, expressed as a percentage of the Remarketing Treasury Portfolio Purchase Price and the Separate Notes Purchase Price or as a percentage of the aggregate principal amount of the Notes to be remarketed, as the case may be.

On the Remarketing Announcement Date, the Company will issue a press release through any appropriate news agency, including Dow Jones & Company, Inc. and Bloomberg Business News containing the Remarketing Announcement.

(d) Each Holder of Separate Notes may elect to have Separate Notes held by such Holder remarketed in any Remarketing. A Holder making such an election must, pursuant to the Purchase Contract and Pledge Agreement, notify the Custodial Agent and deliver such Separate Notes to the Custodial Agent on or prior to 5:00 p.m., New York City time, on the second Business Day, but no earlier than the fifth Business Day, immediately preceding the first Remarketing Date of any Three-Business Day Remarketing Period or the Final Three-Business Day Remarketing Period. Any such notice and delivery may not be conditioned upon the level at which the Reset Rate is established in the Remarketing. Any such notice and delivery may be withdrawn on or prior to 5:00 p.m., New York City time, on the second Business Day immediately preceding the first Remarketing Date of the applicable Three-Business Day Remarketing Period or the Final Three-Business Day Remarketing Period in accordance with the provisions set forth in the Purchase Contract and Pledge Agreement. Any such notice and delivery not withdrawn by such time will be irrevocable with respect to such Remarketing. Pursuant to Section 5.02 of the Purchase Contract and Pledge Agreement, promptly after 11:00 a.m., New York City time, on the Business Day immediately preceding the first Remarketing Date of the applicable Three-Business Day Remarketing Period or Final Three-Business Day Remarketing Period, the Custodial Agent, based on the notices and deliveries received by it prior to such time, shall notify the Remarketing Agent of the principal amount of Separate Notes to be tendered for Remarketing and shall cause such Separate Notes to be presented to the Remarketing Agent. Under Section 5.02 of the Purchase Contract and Pledge Agreement, certain Notes that are components of Corporate Units will be deemed tendered for Remarketing and will be remarketed in accordance with the terms of the Remarketing Agreement.

(e) Unless and until there has been a Successful Remarketing, on each Remarketing Date during a Three-Business Day Remarketing Period or the Final Three-Business Day Remarketing Period, the Company shall cause the Remarketing Agent to use its reasonable efforts to remarket the Notes that the Purchase Contract Agent and the Custodial Agent shall have notified the Remarketing Agent have been tendered for, or otherwise are to be included in, the Remarketing, at a price per $1,000 principal amount of the Notes such that the aggregate price for the aggregate principal amount of the Notes being Remarketed on that date will be approximately (i) if the Reset Effective Date is not the Purchase Contract Settlement Date, the Remarketing Price or (ii) if the Reset Effective Date is the Purchase Contract Settlement Date, the Contract Settlement Price.

(f) In the event of a Successful Remarketing, on the Remarketing Date, the Remarketing Agent shall (i) notify the Collateral Agent, the Custodial Agent, the Purchase Contract Agent, the Company, the Trustee, the Depository and the Clearing Agency of the Reset Rate determined in such Remarketing, the Subsequent Interest Payment Dates and the related

Regular Record Dates, any Modifications by the Company of the Notes and the aggregate principal amount of Notes sold in such Remarketing, (ii) notify each purchaser of the Reset Rate, the Subsequent Interest Payment Dates and the related Regular Record Dates, the Stated Maturity of the Notes and the aggregate principal amount such purchaser is to purchase, and (iii) instruct each purchaser to give instructions to its Depository participant to pay the purchase price on the Reset Effective Date in same day funds against delivery of the Notes purchased through the Depository’s normal procedures. In addition, the Company will request that the Depository notify its participants, no later than the Business Day next succeeding the Successful Remarketing Date, of the Reset Rate, the Subsequent Interest Payment Dates and related Regular Record Dates and any Modifications of the Notes.

(g) In accordance with the Depository’s normal procedures, on the Reset Effective Date, the transactions described above with respect to each Note tendered for purchase and sold in such Remarketing shall be executed through the Depository, and the accounts of the respective Depository participants shall be debited and credited and such Notes delivered by book entry as necessary to effect purchases and sales of such Notes. The Depository shall make payment in accordance with its normal procedures.

(h) In no event shall the aggregate price for the Notes in a Remarketing be less than a price (the “Minimum Price”) equal to (i) in the case of a Remarketing during the Period for Early Remarketing, 100% of the sum of the Remarketing Treasury Portfolio Purchase Price and the Separate Notes Purchase Price or (ii) in the case of a Remarketing during the Final Three-Business Day Remarketing Period, 100% of the aggregate principal amount of the Notes being remarketed. A remarketing attempt on any Remarketing Date will be deemed unsuccessful if the (i) Remarketing Agent is unable to remarket the Notes for an aggregate price that is at least equal to the Minimum Price; or (ii) if a condition precedent to such Remarketing is not fulfilled.

(i) The right of each Holder of Notes that are included in Corporate Units to have such Notes, and each Holder of Separate Notes to have any Separate Notes (together, the “Remarketed Notes”), remarketed and sold on any Remarketing Date shall be limited to the extent that (i) the Remarketing Agent conducts a Remarketing pursuant to the terms of the Remarketing Agreement, (ii) a Special Event Redemption has not occurred prior to such Remarketing Date, (iii) the Remarketing Agent is able to find a purchaser or purchasers for Remarketed Notes at the Minimum Price, and (iv) the purchaser or purchasers deliver the purchase price therefore to the Remarketing Agent as and when required.

(j) Neither the Trustee, the Company nor the Remarketing Agent shall be obligated in any case to provide funds to make payment upon tender of Notes for Remarketing.

Section 7.02 Reset Rate; Modifications. (a) In connection with each Remarketing, (i) the Remarketing Agent shall determine the reset interest rate (rounded to the nearest one-thousandth (0.001) of one percent per annum) that it believes will, when applied to the Notes (with any Modifications as determined by the Company pursuant to this Section 7.02(a) taken into account), enable the aggregate principal amount of the Notes being remarketed on such date to be sold at an aggregate price equal to at least (A) if the Reset Effective Date is not the Purchase Contract Settlement Date, the Remarketing Price or (B) if the Reset Effective Date is the Purchase Contract Settlement Date, the Contract Settlement Price and (ii) if there is a

Successful Remarketing, the Company may elect, at its option, to (A) change the Interest Payment Dates to semi-annually in arrears commencing on the Subsequent Interest Payment Dates; (B) change the Stated Maturity to any other date later than June 1, 2014 and earlier than June 1, 2039; (C) add to, modify or remove altogether redemption rights for the Company; provided that there shall be at least two years between the Reset Effective Date and any such additional or modified redemption date; and (D) add interest deferral provisions to the Notes (each, a “Modification”). Any such election shall be evidenced by an Officer’s Certificate delivered to the Trustee promptly after any Modification is determined. The reset interest rate established on the Remarketing Date on which a Successful Remarketing occurs shall be the “Reset Rate,” and the Reset Rate and any Modification the Company elects shall be effective on the Reset Effective Date.

(b) Anything herein to the contrary notwithstanding, the Reset Rate shall not exceed the maximum rate permitted by applicable law and the Remarketing Agent shall have no obligation to determine whether there is any limitation under applicable law on the Reset Rate or, if there is any such limitation, the maximum permissible Reset Rate on the Notes and it shall rely solely upon written notice from the Company (which the Company agrees to provide prior to the eighth Business Day before the first Remarketing Date of any Three-Business Day Remarketing Period) as to whether or not there is any such limitation and, if so, the maximum permissible Reset Rate.

(c) In the event of a Failed Remarketing or if no Notes are included in Corporate Units and none of the Holders of the Separate Notes elect to have their Notes remarketed in any Remarketing, the applicable interest rate on the Notes will not be reset and will continue to be the Interest Rate.

(d) In the event of a Successful Remarketing, the Interest Rate shall be reset at the Reset Rate as determined by the Remarketing Agent under the Remarketing Agreement. The Reset Rate shall be effective from and after the Reset Effective Date.

Section 7.03 Failed Remarketing. (a) If, by 4:00 p.m., New York City time, on the last Remarketing Date of any Three-Business Day Remarketing Period, the Remarketing Agent is unable to remarket all of the Remarketed Notes at the Minimum Price, pursuant to the terms and conditions hereof, a Failed Remarketing shall be deemed to have occurred, and the Remarketing Agent shall so advise, by telephone the Depository, the Purchase Contract Agent and the Company. Promptly following any Failed Remarketing, the Remarketing Agent shall return, no later than the Business Day immediately following the end of such Three-Business Day Remarketing Period, the Separate Notes submitted for Remarketing, if any, to the Custodial Agent for distribution to the appropriate Holders pursuant to the terms of the Purchase Contract and Pledge Agreement.

(b) The Company shall cause a notice of such Failed Remarketing to be published through any appropriate news agency, including Dow Jones & Company, Inc. and Bloomberg Business News no later than 9:00 a.m., New York City time, on the Business Day following the last Remarketing Date of such Three-Business Day Remarketing Period (which notice, if the unsuccessful Remarketing attempt shall occur during the Final Three-Business Day Remarketing

Period, shall include the procedures that must be followed if a Holder of Notes wishes to exercise its Put Right, as hereinafter defined).

Section 7.04 Put Right. (a) If there has not been a Successful Remarketing prior to the Purchase Contract Settlement Date, Holders of Separate Notes and Holders of Notes that are a component of Corporate Units will, subject to this Section 7.04, have the right (the “Put Right”) to require the Company to purchase their Notes, on the Purchase Contract Settlement Date, at a price per Note equal to $1,000 (or $50 per Applicable Ownership Interest in Notes) plus accrued and unpaid interest to but excluding the Purchase Contract Settlement Date (the “Put Price”); provided , however, that as of the Purchase Contract Settlement Date, Holders of Notes that are part of a Corporate Unit with respect to which a Put Right has been automatically exercised under clause (b) below shall be deemed to have elected to pay the Purchase Price for the Common Shares to be issued under the related Purchase Contract from a portion of the Proceeds of the Put Right of such Notes equal to the Purchase Price in full satisfaction of such Holder’s obligations under the Purchase Contracts, and any remaining amount of the Put Price following satisfaction of the related Purchase Contract will be paid to such Holder.

(b) The Put Right of Holders of Notes that are part of Corporate Units will be automatically exercised unless such Holders (1) prior to 11:00 a.m., New York City time, on the second Business Day immediately preceding the Purchase Contract Settlement Date, provide written notice to the Purchase Contract Agent of their intention to settle the related Purchase Contract with separate cash, and (2) on or prior to 11:00 a.m., New York City time, on the Business Day immediately preceding the Purchase Contract Settlement Date, deliver to the Collateral Agent $50 in cash per Purchase Contract, in each case pursuant to the Purchase Contract Agreement. The Put Price for Holders of Separate Notes shall be applied in accordance with Section 7.04(c) below.

(c) The Put Right of a Holder of a Separate Note shall only be exercisable upon delivery of a notice substantially in the form attached as Exhibit B hereto, together with such Holder’s Separate Notes, to the Trustee by such Holder on or prior to the second Business Day prior to the Purchase Contract Settlement Date. On or prior to the Purchase Contract Settlement Date, the Company shall deposit with the Trustee immediately available funds in an amount sufficient to pay, on the Purchase Contract Settlement Date, the aggregate Put Price of all Separate Notes with respect to which a Holder has exercised a Put Right. In exchange for any Separate Notes surrendered pursuant to the Put Right, the Trustee shall then distribute such amount to the Holders of such Separate Notes.

(d) Notes purchased pursuant to the Put Right shall be cancelled by the Trustee.

Section 7.05 Additional Event of Default. In addition to the events listed as Events of Default in Section 5.1 of the Base Indenture, it shall be an additional Event of Default with respect to the Notes if the Company shall not have satisfied its obligation to pay the Put Price when due with respect to any Separate Note following exercise of the Put Right in accordance with Section 7.04, unless such Notes underlie Corporate Units, in which case the obligation of the Company to pay the Put Price shall be netted against such Holder’s obligation to pay the Purchase Price (as defined in the Purchase Contract and Pledge Agreement) in accordance with Section 5.02 (b) under the Purchase Contract and Pledge Agreement.

CERTIFICATE OF AUTHENTICATION

This is one of the Notes of the series designated therein referred to in the within-mentioned Indenture.

Dated:	THE BANK OF NEW YORK MELLON, as Trustee


	By:
		Authorized Signatory

FORM OF REVERSE OF NOTE

This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”), fully and unconditionally guaranteed (the “Guarantee”) as to payment of principal, premium, if any, interest and any Additional Amounts (as defined in Section 6.01(b)) of the First Supplemental Indenture dated as of June 24, 2009 (the “First Supplemental Indenture”)) by Assured Guaranty Ltd., a Bermuda company (the “Guarantor”) issued and to be issued in one or more series under a Base Indenture (the “Base Indenture”, as further supplemented by the First Supplemental Indenture, the “Indenture”), dated as of May 1, 2004, between the Company and The Bank of New York Mellon, formerly known as The Bank of New York, as Trustee, to which Indenture reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantor, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.

The Notes are senior unsecured obligations of the Company. The Notes will rank without preference or priority among themselves and equally with all unsecured and unsubordinated indebtedness of the Company from time to time outstanding. The Notes will be structurally subordinated to all obligations of the Company’s subsidiaries from time to time outstanding, including claims with respect to trade payables.

This Note is one of the series designated on the face hereof, limited in aggregate principal amount to $150,000,000 (up to $172,500,000 if the Underwriters exercise their overallotment option in full); provided however that the Company, without notice to or consent of the Holders, may issue additional Notes of this series and thereby increase such principal amount in the future, on the terms and conditions (except for issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date) with the same CUSIP number as the Notes of this series.

Unless an earlier Special Event Redemption has occurred, this Note shall mature and the principal amount thereof shall be due and payable together with all accrued and unpaid interest thereon on the Stated Maturity. The “Stated Maturity” shall mean June 1, 2014 or, upon the Reset Effective Date, if the Company elects on the Successful Remarketing Date, any other date later than June 1, 2014 and earlier than June 1, 2039; it being understood that if there shall have been a Failed Remarketing, the Stated Maturity shall remain June 1, 2014. Any Modifications the Company elects, in each case in accordance with the Indenture, shall be effective on and after the Reset Effective Date.

“Subsequent Interest Payment Date” means, following the Reset Effective Date, if the Company elects on the Successful Remarketing Date to make interest payable on a semi-annual basis, each semi-annual interest payment date established by the Company on such Successful Remarketing Date.
